I think it would be a useful feature to automatically fill the filename on Compile with the project’s title metadata tag by default with the field highlighted. I have a feeling for a majority of users this is going to make up a large portion of the file name they’ve prefer and if not it’s only a keystroke away from being cleared.
That appears to be what the Mac version does already. Whether that behaviour is considered as feature-compliance for the Windows version I don’t know I don’t work for L&L.
